A nurse is preparing to administer hydrochlorothiazide 25 mg PO. The amount available is hydrochlorothiazide 50 mg/tablet.

How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies.

(Do not use a trailing zero)

Choice A rationale
Respiratory alkalosis is incorrect. Respiratory alkalosis is characterized by a high pH and low PaCO₂, which is not consistent with the given ABG values. The client’s pH is low (7.22), indicating acidosis, and the PaCO₂ is high (68 mm Hg), indicating a respiratory cause.
Choice B rationale
Respiratory acidosis is correct. Respiratory acidosis occurs when there is an accumulation of carbon dioxide (CO₂) in the blood, leading to a decrease in pH. The given ABG values show a low pH (7.22) and a high PaCO₂ (68 mm Hg), which are indicative of respiratory acidosis. The elevated bicarbonate (28 mEq/L) suggests partial compensation by the kidneys.
Choice C rationale
Metabolic acidosis is incorrect. Metabolic acidosis is characterized by a low pH and low bicarbonate (HCO₃⁻) levels. In this case, the bicarbonate level is elevated (28 mEq/L), which is not consistent with metabolic acidosis. The primary issue is respiratory, as indicated by the high PaCO₂.
Choice D rationale
Metabolic alkalosis is incorrect. Metabolic alkalosis is characterized by a high pH and high bicarbonate levels. The given ABG values show a low pH (7.22), which indicates acidosis, not alkalosis. Additionally, the primary issue is respiratory, as indicated by the high PaCO₂.

Choice A rationale
A high protein diet is not recommended for clients with biliary colic from chronic cholecystitis as it can increase bile production and exacerbate symptoms.
Choice B rationale
A high fiber diet is beneficial for overall health but does not specifically address the needs of clients with biliary colic.
Choice C rationale
A low sodium diet is beneficial for overall health but does not specifically address the needs of clients with biliary colic.
Choice D rationale
A low fat diet is recommended for clients with biliary colic from chronic cholecystitis as it reduces the workload on the gallbladder and decreases the risk of gallstone formation.
